A stator coil finish wire is wedged between the wound coil from which it extends and the stator core at a stator winding station. To accomplish this, a loop is formed in the finish lead and trapped between cooperating surfaces to frictionally resist the wire loop being pulled out by the wire gripper of a lead pull assembly. The wire gripper moves in directions to remove the loop and to wedge the stretch of the lead wire extending through the stator core between the coil and the core. This procedure is advantageously used when winding stators which do not have terminal boards.

Stator coil finish lead positioning

Stator coil lead wires are coursed along complex, circuitous paths on the end of a stator core and trimmed at a precise predetermined distance from the stator core. Improved end effector wire-guiding tooling members are provided in place of conventional gripper jaws to permit the lead wires to be coursed along complex, circuitous paths. In addition, an improved lead pull assembly, improved temporary wire clamps, and a wire former assembly are provided.

In the manufacture of certain stators for dynamoelectric devices, proper spacing between oppositely-facing winding forms of a winding form assembly is determined by the length of a pair of connector rods extending from one winding form to the other. A winding form assembly can be quickly and easily adjusted for use in the manufacture of stators having various stack heights by removal and replacement of the winding form connector rods with connector rods of an appropriate length. The connector rods are locked to one of the winding forms when the connector rods are in a first rotary position and are removable when the connector rods are in a second rotary position. A simple tool can be used to rotate the connector rods between the first rotary position and the second rotary position.
